Problems solved by technology

Certain mechanical issues can affect clutchless multi-ratio transmissions that limit their widespread use; specifically, the ability of such transmission systems to operate effectively and efficiently at high speeds or under high loads in practical applications
Additionally, ratcheting, slippage and tensioning issues can limit the commercial viability of such transmissions by reducing their reliability, reducing their efficiency and increasing wear

Abstract

A pulley assembly (120) for engaging an endless member (118) includes a first pulley (124), a second pulley (126) and at least one transition segment set (128, 130) comprising one or more transition segments (152, 162a, 162b) that are independently movable between an engaged region and a disengaged region to transition the endless member (118) between the first pulley (124) and the second pulley (126). An actuator system (122) includes a support structure (220), an actuator subassembly (222, 226) secured to the support structure (220) and a stator (224, 228). The actuator subassembly (222, 226) includes a follower (250) and a sled (248), which is movable in a circumferential direction between an advanced position and a retreated position, in response to an electromotive force generated onthe sled (248) by the stator (224, 228). The follower engages the cam surface (262) of the sled (248) to move in an axial direction between an extended position and a retracted position as the sled (248) moves between the advanced and retreated positions.

Description

[0001] Cross References to Related Applications [0002] This application calls for a U.S. provisional patent application filed on March 14, 2018 and titled "Electrical System Features, Screw Drive Configurations, and Advanced Geometry Design for Sheave Segment and Support Surface Design in Synchronized Segment Interchange Pulley Transmission Systems." The benefit of Patent Application No. 62 / 642,979, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates generally to transmissions, and more particularly to a pulley assembly and actuator system for a range pulley transmission. Background technique [0004] Transmissions are well known and can be used to vary the transmission ratio between rotating elements. Potential applications for transmissions are vast and include motor vehicles, human-powered vehicles, marine vehicles, and heavy machinery such as pumps, turbines, mixers, winches, centrifuges, and shred...
